If I were you I would start a new thread about the bubble on her neck and post photos there - perhaps that will draw in some more medical advise than I have to offer.
That is really odd. I hope someone else can weigh on and help you. Do you have an Avian vet anywhere near you? Did you find the vet wrap and try with their legs?
@isaac o might be able to help you if you can get a more clear picture of the bubble area. How long has she had it? Is this a picture from today? How old are they?
I was trying to figure out what I was seeing there. Can you get a close up photo of that? Has she always had it? Has it grown? Does it bother her? What did the vet say about it?
It sounds like you're really trying to help them! It can be so hard sometimes with these little ones who have needs...
If you're giving it through syringe it looks like 1 mil a day, very carefully to the right side of the ducks mouth. You have to go slow and be careful it doesn't go into their lungs. Try it over treats first. Have you looked at the special topic "Niacin Deficiency in Waterfowl" that is found at...
Oh goodness, I guess you need to give more information then about what you observed when it started. You wouldn't want to hurt them or make it worse! Maybe you can attach pictures or video. With my duckling I noticed she started having difficulty getting up from a seated position, despite the...
Because they've been scooting for a couple weeks now you're probably going to have to do some extra work with them to get them back to standing and walking. If it was me, I would go for the Vitamin B complex - just because it works so amazingly for leg issues. I would tape their legs into...
When I did the vet wrap I initially had someone help me stand her up and put her legs in what would be proper position, then just go around a couple times with vet wrap. I might have put a little wrap first on each leg and then wrapped them into position to have the vet wrap stick to that.
How old are your ducklings? Do you have them on liquid vitamin B complex? This is the best way to quickly get them what they need for their legs. I had a duckling develop splay leg a couple years ago. She initially was walking, then just started laying much more, and having difficulty standing...
